  • My iMac wont wake up from sleep

    My first gen iMac G5 1.8 20" wont wake up from sleep. Always I have to plug out and then in the power cord from the outlet then I can turn on the computer.
    Any suggestion?
    Or is this the Apple's known The iMac G5 Repair Extension Program for Video and Power Issues?
    PM QUAD 4.5GB Ram 30" Dell,RAID 0 WD Raptors+1.2TB Maxtor disks with G5 jive   Mac OS X (10.4.8)   iMac G5 1.8 Ghz,Mac mini intel & mac mini PPC, 24" Dell

    You could also try the following;
    If your Mac happily goes to sleep but won't wake up--Hold down the power switch to force-reboot your machine and get it running again.
    Don't worry-your Mac isn't narcoleptic. Its Open Firmware system or NVRAM (nonvolatile RAM) is likely corrupt, and your Mac can't remember how to wake up.
    Restart your Mac and immediately hold down the Command-Option-O-F key combo until you see a somewhat intimidating command-line display that ends with the Open Fimware prompt. Type the following line:
    reset-nvram
    press the return key on your keyboard
    set-defaults
    press return
    reset-all
    press return
    Your Mac will reboot. Once it's running, put it back to sleep to test. If the problem recurs your Energy Saver preferences may be the culprit. Delete the com.apple.PowerManagement.plist file (go to Finder/Hard drive/Library/Preferences/SystemConfiguration)--don't worry, your Mac will regenerate a new one--and then restart to see if that rights the wrong.
    Still didn't work? Might be time to call AppleCare or see an Apple Genius or a technician.

  • 1 week old iMac wont wake up from sleep?

    Hello all.
    I have brought the 21,5" iMac 1 week ago. I just chosed the preconfigured model.
    But i have had some problems with it.
    When the computer has been to sleep for some hours, it wont wake up with click on keyboard or on the mouse. I will have to use the powerbutton, where the computer then comes with a error, but it starts up.
    What shall i do? It have had the issues from the day i got it.
    Thanks.

    Are you running OS X 10.6.2 as indicated on your profile? The OS has been updated a few times since then, in fact OSX 10.6.5 was released last Wednesday. You can download the combo updater here: http://support.apple.com/kb/DL1324
    It's often advised to 'repair permissions' before and after updating. Utilities>Disk Utility - select Macintosh HD on the left and click on 'repair permissions'.
    I seem to remember that some sleep/wake issues were addressed in one of the earlier updates. The combo updater will have all previous updates/revisions incorporated into it.

    You have a lovely intel machine, you lucky thing. However, this forum is for PPC G5 iMacs, you need to post on the [intel iMac forum|http://discussions.apple.com/forum.jspa?forumID=1110].
    Hope you find a solution,

  • TS1367 I am asking this question about my 27 inch iMac Desktop Computer. I normally use my Laptop and very seldom use the desktop but was going to download the new software earlier today. I could not wake it from sleep.

    The other evening we had a storm and lightening hit a house a few doors from me. It jolted my chair but that seemed to be all here. I use my laptop most of the time but since there was a software download I went to my 27 inch iMac and could not wake it from sleep. The light on the keyboard is not lit either. I have this connected to a Battery Backup Power so do not know what has happened or what to do. When I push the power button to try to turn it on nothing happens. There is no shound, no video, nothing; however the disk drive that does my time maching backup has a light on it and the other things that are plugged into the battery power pack also have lights on them. The printer is on and says it is ready to print. Since I cannot boot it up I do not know what to do to even try to get it started. I did not know what would happen if I put the first start up disk in  the external disk drive and try that or not. The internal drive is broken. I do not have any repair shops or apple stores around me at all less than 150 miles away and I am disabled with 24/7 help and oxygen so can not take it in. Are there any suggestions that anyone can give me. I have not been able to find any way to reset the backup battery pack either. It is a Tripp-Lite. Any help anyone can give will be greatly appreciated. Thanking you in advance for your time and trouble.

  • My imac freezes , need to restart everytime i wake it from sleep mode. just started happening 2 weeks ago.

    For about 2 weeks whenever I return to my imac and tap the mouse to wake it from sleep mode my screen is frozen. I have tried to wait for it to unfreeze but it doesnt wake. I cannot get any results from using the mouse or the keyboard. I always have to hard reset the computer to be able to use computer again. My mac is a year old. Anyone have any thoughts as to why tis is happening? Thanks

    If you have more than one user account, these instructions must be carried out as an administrator.
    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
    Step 1
    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
    Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged before the boot, while the system was unresponsive or was failing to shut down. Please include the BOOT_TIME message at the end of the log extract.
    Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
    Please do not indiscriminately dump thousands of lines from the log into a message.
    Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
    Step 2
    Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

  • My iMac will not wake up from sleep after upgrading to OS X Mavericks

    After upgrading to OS X, my iMac will not wake up from sleep.  Each time I have to do a hard restart.  Is there a fix for this problem?

    Hi,
    I have just had the same problem with my iMac and after upgrading to Mavericks my iMac would not wake without pressing the power off button and re-booting.
    Anyway, I have since done a complete new install on my iMac and have gone 5 days without an issue with the iMac not waking.  It was a bit of a pain to do but my own view so far is that the problem is linked to the upgrading of the OS instead of a clean install.
    My iMac now flies with a new OS installed instead of an upgrade.

  • IMac wakes up from sleep independently

    My iMac wakes up from sleep mode. Sometimes I have to login, sometimes not. Time Machine is inactive because the external HD is not connected. I´m a new Apple-User, switched just about 14 days ago to Apple and I don´t find a solution for my problem.

    I have the same issue.  I'm also not using Time Machine on my iMac.  It happens within the same couple of hours every few evening.  I think it might be a process / update that is looking for updates in the background.  I think I'm going to check the logs next time it happens.

  • Alu iMac wakes up from sleep every night

    Since I have installed the last Leopard Security Update my iMac wakes up from sleep every night at 1 pm.
    Enyone has an explanation?

    I have the same problem, i am located in France and the wake up tile is also 1:00 AM i have some doubt about Elgato Eye TV could be the root cause.
    I have seen that in main admin account the eye tv helper task is lauch during logging.
    I remove it, and the mini does not wake up this nignt, but ...
    When i launch Eye TV, it installed again eye tv helper task...
    Are you also and elgato user ?

  • IMac G5 iSight will not wake up from sleep

    This has been happening to me for some time.
    Occasionally my Mac do not wakes up from sleep. Instead it hangs!
    Here how it goes:
    I press a key on keyboard; my Mac wakes up, but screen remains black with only mouse pointer. I cannot see login window.
    And Mac stays this way for hours. No matter if I press a key, click a mouse.
    The only remedy is to press power button and to shut it down.
    Then I have checked console.log. Nothing spectacular. Here is log from last accident:

    Wait - before you take it in for repair or get put on hold with Support try this:
    Go to System Prefs, Energy Saver, then set your display sleep and computer sleep times the same. Check both check boxes too.
    Trust me, I've been working on this problem with Apple and checking the discussion boards for over a year now. I've had my logic board replaced, power supply replaced, been through about 8 Apple techs and tried just about anything you'll read on these boards or get told to do by a tech. If you notice about every 4th or 5th page has someone posting about this problem. The above suggestion is the most recent thing I tried (from reading posts here in this forum, not from an Apple Tech) and it has come out of sleep for the past 30+ tries without a problem. This is not to say this is IT(the final sovle), because it has been known to go on a good run for a week or so and then come up again. This 'fix' however, has been the most promising. If it continues to work, I will let Apple know and hopefully they can fix the bug. They have all sorts of case history with me on this problem.

  • Thunderbolt ethernet not working when computer wake up from sleep.

    thunderbolt ethernet not working when computer wake up from sleep.
    it will not happen in Mountain loin.

    I had this problem on SL and on Lion as well, and it occures for WiFi and Ethernet connections.
    In fact the internet connection was not broken as I could ping the destination usin the IP (not DNS name).
    In this case the problem was related to mDNSResponder task which handles all dns queries.
    It was the most frequent problem in my day to day work with SL and now Lion. It was never fixed by any patch from Apple. I tried almost all voodoo including fresh install, all possible config changes - no solution.
    The only version with no problems related to network was 10.5.8. All the other versions had issues of different kind (WiFi instability (lost signal), DNS problems (for wireless and wired connection) sometimes associated with machine sleep and wake up and sometimes with no reason.
    QUESTION: Is your problem independent of the access point / router you connect to.
    I must say networking was (and still is) the weakest part, besides the other OS X weaknesses I experienced during 4 years of OS X usage.
    No problems in the same network with Linux or Windows beeing ran natively on my iMac So hardware is OK.
    Software is of poor quality. Not much more to say in this matter.
    I found a very interesting article dated 1996 about programming which I think is still valid.
    Link to the article: http://www.fastcompany.com/magazine/06/writestuff.html

    Software is everything. It also s***s.

  • OSX 10.7.5 How can I make my computer wake up from sleep?

    My computer won't wake up from sleep whether I put it to sleep by a hot corner or by closing the lid.  Has anyone a solution, plezase?

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and  Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • 10.4.8 - Wake-up from sleep issue: Workaround

    I eventually got rid of wake up from sleep issues on my PB G4, which I had systematically experienced since I upgraded to 10.4.8.
    Here is a workaround for those who have customized their EnergySaver:
    - the display and the computer must not go idle at the same time ; just select different timeouts.
    For those whom it may help.
    MacBook Pro - PowerBook G4 - iBook G3 - iBook G4 - iMac G3   Mac OS X (10.4.8)  

    Actually, another workaround seems to work much better when my PB's display a black screen after wake-up from sleep :
    - close the lid
    - wait for a few seconds
    - re-open the lid.

  • Won't wake up from sleep mode

    I have only had my iMac for a couple weeks and four times now it won't wake up from sleep mode. I have to use the on/off button for a response.

    Since you have a new machine, I would call Apple immediately and have them deal with the problem.
